Application filed June 20, 1916.

vlllaterial,"of which the following is a specification;

- This.invention-relates to improvements in ap aratus' for eitecting thedestructive distillation of carbonaceous materials, in acdescribed in00-. filed Nov. 24,

means for accurately controlling the temperature in each of a series ofdifferent zones in a retort according to the distillates required fromthe particular zones.

Other objects of the invention will appear more fully hereinafter.

The'invention consists substantially in the construction, combination,location, and arrangement of parts, all as will be more as shown in theaccompanying drawing, and finally pointed out in the appended claim.

In the construction and operation of a distillation retort it haspreviously been proposed to withdraw different volatile products fromdiiferent parts of the distillation retort heated to differenttemperatures, and quickly to condense such products simultaneously. Thepresent invention relates to distillation apparatus operating on thisprinciple; and it consists in a simple and efiective constructionand-arrangement whereby the desired results are secured, and which Willnow be described more in detail.

Figure 1 of the accompanying drawing illustrates the improvement asapplied to the invention of copending patent application Serial No.63,335, filed November 24:, 1915, and Fig. 2 is a plan view Referring tosaid chamber retort carried in a furnace setting having end walls A andE, and the partition walls, 13, C, D, definitely dividing up the surfaceheating tlues into compartments 9, r, 8, t, and separate burners u, 'v,w, w, are arranged in the respective compart ments, each controlled by asupply regulilting valve F, G, ll. 1.

The several supply pipes are connected which may in turn be suppliedeither from the gassupply 0, coming from the retort r1. lhrough the condensers, per the pipe n, or from an independent supply .l. or rom both.lhe gases from pipe a return to the pipe n, the gas being drawn by anysuitable pump, such as the eentri lugal pump Z, tln'ough the pipe 'n'and are delivered to the pipe R connecting to n.- intern'icdiately thegas is passed through cooling ap 'iaratus of any suitable a cylinderwith Water trays, or dropping spray--indicated by.

The gas passage preferably has a branch. S through which gas is taken tothe heating gas pipe 79 as it isnot necessary to be cooled, if this isto be used for heating.

As above stated volatile matters are directly and simultaneously removedfrom the retort a by pipes 1, 2, 3, a, such volatile matters varyingaccording to the temperature in the several zones of the retort, andthey are immediately conr' lensedin a series 0 e]ector condensers 'e, f,g, h, by cool gases medium when densers e, f, f],

A suitable example of the flue design is indicated in Fig.2; K, L, M, N showin the dampered openings to the flueT; w ich may be ofsheet metal, and 7), 0, (Z the dampers regulating" the openingsthrough], the partition walls 7 l}, C, D.

Air for combustion 'ii'paybe conveniently amovable fire bricks when notrequired, or

by means of dampers of ordinary design. The final product from theconveyer will be coke, and in order to get this of a harder character, achamber strewn dotted at t may be employed in which the coke coming outor the delivery chute is heated up to about 800 degrees 6., the saidchamber being provided with an additional heating burner 11 controlledby valve Y.

Although a single conveyer chamber forms a unit in itself, there may ofcourse be several units in a complete plant.

By means of this invention successive tones of the retort may proceedeither with a gentle and a successive temperature increase, or bytemperature diiierences of considerable amount, or again by an increaseand then a decrease as may be desired.

' esaeee What I claim as new and useful and of my own invention, anddesire to secure by Letters Patent, is

In an apparatus for distilling volatile matters from solid carbonaceousmaterial, the combination of an elongated retort, a plurality of heatingcompartments surrounding successive portions of the length thereof,thereby establishing Zones in said retort, independently regulatableheating means in 'each of said compartments, a conveyer in the saidretort for conveying a solid material through the length of said retort,said conveyor substantially filling V the cr0ss-section of said retort,ejector condensers, a plurality of vapor outlets one connected to eachof the several zones of the retort, said outlets each being connected toan ejector condenser, and means ior suplin cool 'ases to each of saidsector
